COMBINED TYPEWRITING AND COMPUTING MACHINE.

Application filed October 18, 1921.

To all whom t may concern:

Be it known that I, FREDERICK U. CON- ARD, a citizen of the United States, residing in Brooklyn Borough, in the county of 6 Kings, city and State of New York, have invented cert-ain new and useful Improvements in Combined Typewriting and Computing Machines, of which the following is a specification.

The present invention relates to combined typewriting and computing machines, and is herein disclosed as applied to a machine of the Underwood-Hanson type.

In machinesof this type, selectors, settable at the desired column positions on the typewriter-carriage, engage, seriatim, and successively set Certain denominational elcments as the carriage is given its stepbystep letter-feed movement through the printing zone by operation of the numeral keys. Naturally the digits comprising any numi ber are written inthe printing zone from higher to lower denomination (that is to say, from left to right on the paper), and the register wheels, or their equivalents, are similarly arranged. The carriage, however, feeds to the left, and the selectors thereon therefore. pass the register in a direction frOm the lower to the higher denominations there- 3 of. 'lransposition means have therefore been employed to cause the selector on the carriage, when in a lower denominational position with regard to the register, nevertheless to set the computing mechanism for 35 registering thereon the digit of highest denomination to be printed, and successively to set lower denominational computing elements as the carriage continues its movement to the left.

An object of the invention is the provision of means for effecting a left-to-right movement of the settablc selectors, thereby eliminating the complicated transposition mechanism above referred to, and greatly simplifying the machine. In the preferred form of the invention, I effect this object thereof by providing a second or sub-carriage' for the settable selectors and by causing such sub-carriage to be so controlled by the movement of the main or platen carriage as to move with the latter, but in opposite direction.

l am aware that U. S. Letters Patent to L. A. Wernery, No. 1,389,232, granted Au- Serial No. 508,434.

gust 30, 1921, shows means for amplifying 1n the register the ordinary letter-feed spaces. It is an object of the present invention, however,` to effect such amplification while maintaining a continuous connection between the platen and sub-carriages; and while providing a sub-carriage on which the selector' or a number of selectors may be set in any desired column positions.

t In the preferred embodiment of the invention, the control of the sub-carriage from the main carriage, and the amplified and reversed direction or movement of the sub-carriage are obtained by means of racks on the tuo carriages on opposite sides of a shaft havmg gears of different pitch diameters in mesh with the racks.

(lther features of the invention are a fanlike spread of the selector-actuated members of thc (omputing mechanism, whereby a further amplification of the register is had, and means by which the amplification effected by the gearing between the carriages is combined with that effected by the spreading of the selector-actuated members.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a view, in side elevation, of a combined typewriting and computing machine embodying the present invention and showing the parts associated therewith.

Figure, 2 is a plan View of the mechanism shown in Figure 1, certain parts being omitted for the purposes of clearness.

Upon depression of alphabet keys 1 and numeral keys 2, motion will be transmitted, through key-levers 3 and bell-cranks 4, to type-bars 5, carrying upper and lower-case types 6 and 7 to cause the type-bars to strike against a platen 8, revolubly mounted in a platen-frame 9 supported in a carriage 10 for sliding movement on rods 11 and 12.

Upon approach of any type-bar 5 to the platen 8, a 'heel 13 on the type-bar will strike the front of a universal frame 14 to drive the same against the resistance of a spring (not shown), to actuate the usual fixed and loose dogs 15 and 16, so that the dogs will alternately engage escapement wheel 17 and permit step-by-step feeding movement of the carriage under the urging of the usual spring-barrel (not shown). Operative connection between the escapement Wheel 17 and the carriage 10 is obtained by means of a pinion 18 having the usual one-way pawl connection (not shown) with the eseapement wheel 1T and meshing with a rack 19, having the usual pivotal connections (not shown) with the carriage 10.

In order rapidly to position the carriage, provision is made of decimal tabulator keys and connections (not shown) to lift plungers 20 into engagement with suitable stops 21 adjustabl)v mounted on a rack 22 on the typewriter-carriage. Means, not shown but which are old in the art, are also provided for releasing the carriage l0 from the escapement mechanism whenever one of the tabulator plungers .2O is lifted.

Infaddition to actuating corresponding type-bars 5, the numeral keys serve to set up computations which later are run into a register or registers. For this purpose, each of the numeral keys 2 has pivotally connected therewith a depending thrust-,link 23, which is positioned to engage an arm 24 mounted on a rock-shaft 25. It will be un` derstood that there is one of such rockshafts for each of the numeral keys, and that each of the rock-shafts has suitable operating connections with a pin-setting linkage, of which the lower bar 26 serves to engage and set pins 27.

These settable pins 2T are arranged in longitudinal rows extending from front to back of the machine, and each of said rows is mounted on a denominational member shown in the form of a rack-bar 28. Pins of the same number on the different bars` 28 lie in rows transverse of the machine and slight-ly to the rear of the corresponding pin-setting bars 2G. The rack-bars 28 determine the denomination of pins set, and the setting bars 26 determine the value of the pins set on any of the rack-bars.

The rack-bars 28 are advanced seriatim by mechanism, hereinafter described, to enable setting of the index-pins thereon. After the pin-setting has been completed. a general operator 29 is actuated (in the usual way) to move it forwardly, and the bars 28 are advanced through the engagement of a bar 30 on the general operator with such of the pins 27 as have been depressed by the bars 26. lVhen the bars 28 are thus advanced, racks 31 thereon, in mesh with pinions (not shown) on the dial-wheels 32. run up on the dial-wheels the computation set up on the pins 27. Carry-over mechanism 32a from one dial-wheel 32 to the dialwheels of higher denomination is provided. The mechanism thus far described is well known in machines of this type.

As the carriage is advanced from one column position or computing zone to another, and as it is advanced step by step through any computing zone by operation of the numeral keys, a rack 33, fast to brackets or rearwardly-extending arms 34 on the carriage 10.and meshing with a pinion 35 on a vertical shaft 3G having-bearings in arms 3T projecting from therear of the machine, causes the carriage 10 in its translatory movement to transmit a corresponding rotary movement to the shaft 36, and through the latter to a pinion 38, of larger pitch diameter than the pinion 35, fast on the shaft 36 at the foot thereof. The pinion 38 meshes with a. rack 39 on another or sub-carriage 40, which is mounted at the rear and near the base of the machine to move at all times in a direction opposite to that of the movement of the platen-carriage. This opposite direction o-f movement is effected by reason of the racks 33 and 39 being on opposite sides of the shaft 36.

The carriage 40 is shown as comprising an inverted U-shaped frame-piece, and is mounted to slide on two rods 41 and 42 supported in plates or brackets 43 secured to the rear of the machine. To provide for eas movement of the carriage 40 on the ro s 41 and 42, there are at the rear of the carriage 40 anti-friction rolls 44 and 45, carrie( on stub-shafts, and respectively engaging the rod 42 at the top and bottom thereof. Also on stub-shafts at the front of the carriage 40 are anti-friction rolls 46 and 47 engaging the bar 41, respectively, at the top and bottom of the latter. The carriage 40 is held anti-frictionally against forward and backward displacement by reason of the rolls 44 and 45 being grooved where they engage the rod 42, and by reason of rolls 48 mounted on vertical stub-shafts 49 on brackets 50 on the carriage 40, which rolls 48 bear on the front face of the rod 41.

The denominational selecting mechanism of the present invention is as follows. Supported in the end plates 51 of the carriage 40 are two rods 52, 53, the rod 53 being notched on its front face, as indicated at 54. The denominational selectors 55, 56 are slidably and pivotally mounted on the rod 52; the pivotal movement ofthe selectors adapting a depending portion or nose 57 thereof to be swung in and out of the notches 54 on the rod or rack 53, so that, after sliding the selectors on'the rod 52 to any desired column position, the same may be held in that selected column position. As is well understood in the art, the purpose of these dcnominational selectors is to effect a seriatim setting of the rack-bars 28 as the typewritercarriage moves through the computing zone; that is to say, to move, seriatim, the rackbars 28 slightly forward against the usual springs 28a, so as to bring the pins 27 thereon in register, or in effective position, under the bars 2G; it being Aobserved in Figure 1 that,` in the normal or ineffective position of the rack-bars 28, the pins 27 are slightly to the rear of their corresponding operating bars 26. In the machine shown in the drawings, there are two sets of rack-bars 28 and associated parts, because in this machine two registers are provided. The selector 56 has to do with the connections to the lefthand set of rack-bars 28, and the selector 55 has to do with the right-hand set of rackbars 28.

The immediate means for moving the rack-bars 28 forward `to pin-setting position are levers 58, one for each rack-bar 28 and all mounted to swing on a shaft 59 fast to and extending longitudinally f the main frame of the typewriting machine. Each of the levers 58 has a nose 60 in alignment with its corresponding rack-bar 28 lto engage the rear end of the latter, and to force the rackbar forward when the lever 58 is swung forward on its pivot 59. It is this forward swing of the levers 58 which it is the purpose of the selectors 55 and 56 to effect; and, in order that. this forward swing may be effected, the levers 58 have rearwardly-exftending fingers 61 thereon, terminating in faces which are adapted to be engaged by dogs 62 on the selectors as the typewritercarriage 10 imparts a reverse movement to the selector-carrying carriage 40.D

As shown in the drawings, the dogs 62 lie in horizontally-disposed grooves in the selector members, and are pivoted therein, as at 63, to have a limited lateral swing; springs 64 being provided to hold the dogs in their Figure 2 position in the selectors, and to return the dogs to their Figure 2 position after the same shall have been moved from such position. The swiner of the dogs 62 is to the right from their 4igure 2 position, the dogs being held from a leftward swing by the interior faces of the grooves in which they are set. The purpose of having the dogs pivotally mounted in the selectors is to permit the same to swing back and thus to pass the fingers 61 on the rack-operating levers 58 when the carriage is returned, so that the machine may not be blocked. In order that the dogs in the forward movement of the carriage may effectively engage and operate the levers 58, their noses are inclined or provided with cam surfaces 65, as indicated in Figure 2.

Except when in and entering into the selected computing zones, it is not desired that the selectors be in effective position. Consequently, the selectors, as indicated by the position of the selector 56 in Figure 1, are normally so disposed that the dogs 62 thereof are below and out of register with the ends of the fingers 61 on the levers 58. The selectors assume this ineffective position by reason of gravity; the notches 54 in the rack 53 being deep enough to permit of such gravity of movement of the selectors. Furthermore, when the machine is not being used for computing purposes, it is desired that the selectors be at all times in this ineffective position. Consequently, there is provided hand-operated means for setting certain controls which will lift the selectors at the computing zones when computing is desired, such controls being themselves ineffective except when this hand-operated means is set in computing position.v

For so setting the selector controls, there is provided a key-lever or push-button 66 on the end of a shift rod 67, which is moved forward and backward in the machine, and which is provided with a pin 68 working in an Lshaped slot 69 in the machine frame, the L or offset portion 70 of the slot permitting the rod 67 to be slightly depressed after it has been pushed rearwardly, so that the pin 68 may enter the offset of the slot and serve to lock the rod 67 in its rearward position to maintain the selector setting or control parts in effective osition. At its rear end the rod 67 pivotal y connects to the upper arm of a lever 71 mounted on a pivot 72 on a bracket 73 on the main frame of the machine.

lVhen the rod 67 is given a rearward thrust, the lower arm 74 of the lever 71 engages and rocks forward an arm 75 fast to a rock-shaft 76, which has bearings in brackets on the rear of the main frame. Also fast to the rock-shaft 76 are two sets of arms 77. Each set of arms 77 comprises two arms between and by means of which is held a roller 78, there being one such roller for each set of denominational rack-bars 28 and associated parts. The rollers 78 are tapered at 79 at each end thereof. Each of the selectors 55 and 56 carries a roller 80 which is likewise tapered, the rollers 80 being adapted, upon movement of the carriage 40, to engage the tapered ends of the rollers 78, and thereby to mount upon the rollers 78 and cause the selectors to be moved up, so that the dogs 62 thereof may register with fingers 61 on the rack-operating levers 58 that is to say, when the rollers 78 shall have been themselves moved up into the path of the selector rollers 8O by operation of the key 66 and thrust rod 67. Normally, the rollers 78 lie in the path of the selector rollers 80, so that the selectors may be operated until the key 66 is actuated, after which no setting of the selectors is effected. A spring 81, connected at one end to one of the arms 77, and at its other end connected to an arm or bracket 82 on the frame, normally holds the rollers 78 in the path of the rollers 80, and returns the rollers 78, arms 77, shaft 76 and arms 75 to such normal position when the rod 67 has been lifted to release the pin 68 thereon from the offset 70 of the slot 69. A stop 83 on the arm 82, by engage-ment with one of the arms 77, determinesthe normal position of the rollers 78.

As shown at 84 in Figure 2, each of the levers 58 which actuate the pin-bars 28 is offset at its rack-bar-engaging end; the levers 58 on one side being offset to the right and the others being offset to the left, t us effecting a considerable 'fan-like spread. The pin-bars 28 register with the ends of the oii'sets 84, and, therefore, as shown in Figure 2, the spacing of the pin-bars 28 is considerably greater than that of the arms of the levers 58. By reason of the difference in size of the pinions and 38, the spacing between the levers 58, as shown in Figure 2, is considerably greater than the letter-feed spaces of the typewriter-carriage. The spacing of the register elements therefore represents a combination of two amplifcations of the letter-feed spacing.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:
